Welcome to our interactive data dashboard where you can gain easy access to the main statistics about Welsh speakers in Wales. It uses 2021 Census data, the main authoritative source for the number and percentage of Welsh speakers.
You can use it to get detailed data about exactly where Welsh speakers live and see how patterns have changed over time, as well as find out more about the lives of these speakers.
Our goal is to put the data in your hands and support you to easily find the information you need. Whether you're a researcher, educator, or simply someone interested in Welsh and its speakers, we hope you enjoy using it.
